750 W ATX 3.1 power supply

This fully modular ATX unit delivers 750 W of continuous power and meets the ATX 3.1 and PCIe 5.1 specifications. A native 12V-2x6 connector is included for current-generation graphics cards. Japanese main capacitors and a 120 mm rifle bearing fan support reliable, low-noise operation. 80 Plus Gold certification confirms efficiency above 90 % at typical loads.

Suits modern GPU builds.

Builders assembling a system around a single PCIe 5.1 graphics card will find the native connector and full cable modularity convenient. The four 6+2-pin PCIe connectors also cover most dual 8-pin cards. Systems that require more than 750 W or multiple 12V-2x6 connections should consider a higher-capacity design.

Native 12V-2x6 connector for PCIe 5.1 graphics cards

The single native 12V-2x6 cable is the deciding specification for compatibility with the latest graphics cards that require this interface. Four additional 6+2-pin PCIe connectors and four SATA power connectors handle the remaining components. Full modularity lets you install only the cables your build needs.

Questions about this item

What cables come in the box and what must I source separately?

The unit ships with a full modular set including a native 12V-2x6 cable, four 6+2-pin PCIe cables, four SATA power cables and a 20+4-pin ATX cable. No extra cables are required for a standard build.

How do I decide between the available versions or capacities?

This model is a single 750 W capacity with ATX 3.1 and PCIe 5.1 support. Choose it when your GPU needs a native 12V-2x6 connector and your total system draw stays within 750 W.

What does the 91% efficiency figure mean once the PSU is installed in my PC?

At typical loads the unit converts up to 91% of AC input into usable DC power, so less energy becomes heat and your electricity draw is lower than with a lower-rated supply.
